Perfect fit for both Mitsubishi and CAT applications.

We've used this alternator on both a Mitsubishi 6D22 generator and a CAT 320B. The mounting points and pulley alignment were exact for both applications. The 24V output is stable and the build quality is excellent. Great to have one part that fits multiple machines.
